Description

M/A-COM’s MASW-007587 is a broadband GaAs

PHEMT MMIC diversity switch available in a lead-

free 3 mm 12-lead PQFN package. The MASW-

007587 is ideally suited for applications where very

small size and high linear power are required.

Typical applications include 2.5 & 3.5 GHz WiMax,

WLAN MESH networks, fixed wireless access, and

other higher power systems. Designed for high

power, this DPDT switch maintains high linearity up

to 4.0 GHz.

The MASW-007587 is fabricated using a 0.5 micron

gate length GaAs PHEMT process. The process

features full passivation for performance and

reliability.

3. For positive voltage control, external DC blocking capacitors are required on all RF ports.

4. Insertion loss can be optimized by varying the DC blocking capacitor value. For use above 2.5 GHz, M/A-COM recommends using

smaller capacitor values. For example, use 5 pF for 3.2 GHz.
